myBiorhythm lets you visualize the Biorhythm for a given Birthday for Today or at any given Date. It has an Overview of the best and worst Days for the selected Year and also show's you the Percentage and the Icons on your Apple Watch as App or Complication.

According to the theory of Biorhythms, a person's life is influenced by rhythmic biological cycles that affect his or her ability in various domains, such as mental, physical and emotional activity. These cycles begin at birth and oscillate in a steady fashion throughout life, and by modeling them mathematically, it is suggested that a person's level of ability in each of these domains can be predicted from day to day. The theory is built on the idea that the biofeedback chemical and hormonal secretion functions within the body could show a sinusoidal behavior over time.

The free Version only offers the primary Values, via InApp Purchase you can upgrade to the full version and benefit from additional Values plus the combined Line and another View that shows you the best and worst Days of the Year.

Works great!

The date needs to be set by tapping on the top line. It will show one day later but the biorhythms are accurate for the birthday entered. I bought the pay version and all the categories work great! I gave it 4 stars because of the date glitch. Otherwise once set you can forget about it.



Terrible. I had to re-write my card info. The dates were wrong. Tiday’s date and my birthday were off by one day. I immediately deleted it and got one that functioned.
